Overprice housing and then lower it weeks later, so that people have already been bankrupted trying to just get a smaller house (which they can't then sell back for the gil they spent), and so that people will have spent however much time being bored out of their minds (and getting annoyed at the game) grinding/farming so they can scrimp together enough for the house? After the economy has been further screwed up by everyone trying to sell everything at once? And making it very difficult for people who actually use the things like apkallu eggs to get their hands on them, due to people trying to farm the crap out of them just for extra gil...?

Yeah, that's a *great* idea.
